Claims. (01. 183-11) This invention relates to an appliance which may be conveniently referred to in the art as an automotive air cleansing device, that is an auxiliary structure which is adapted to' cleanse air supply to the carburetor to enhance the operation of the motor.

invention will become more readily apparent from the following description and drawing.

On the drawing:

,Figure l is a vertical sectional view through an air cleansing device constructed in accordance with the present invention.

Figure 2 is a horizontal sectional view taken approximately upon the plane of the line 2-2 of Figure 1.

Referring now to the drawing by reference numerals it will be seen that the reference character 3 designates a suitably shaped casing having outstanding attaching brackets 4 connected with an appropriate relatively stationary support 5. The casing is provided at its top with a clean air conduit or outlet 6 and provided at its bottom with a skirt-like portion '1 fitting telescopically into a cup-like liquid container 8 adapted to contain a predetermined quantity of oil in the space 9 and form an oil sump. The cup-like container '8 and the skirt portion of the casing are provided with outstanding lugs II) with which connecting bolts H are connected to hold the two parts in this telescopic relation. Within the casing is a screen I2 forming an upper compartment which contains a filtering wad of material l3 of appropriate texture. This is of porous nature and allows the air to pass upwardly therethrough and removes the oil particles from the. air. The reference ing wall of the cup-like receptacle 8. Inside of this receptacle is an arcuate partition wall defining an oil reservoir or trough 2|. Extending up from this and into the chamber I5 is an oil induction spray tube 22 which may be conveniently designated as a percolating tube. This has a flared bottom 23 and oil intake ports 24. At this point is an appropriate stuiling box or packing gland 25 to which a hot air pipe 26 is connected. The hot air may be gas from the exhaust manifold of the engine. In any event a motive gas under pressure is employed. This pipe is in turn connected at its opposite end (in a manner not shown) with theexhaus't manifold. It is intended to supply a stream oflhot air into the tube 22.

In operation the atmospheric air enters through the intake of the air supply'tube lB'and passes in a stream through chamber IS. The stream of hot air or exhaust gas passes through the pipe 26, acts on the 011 column within the percolating tube 22, and causes the oil to literally boiland to bubble upwardly through thetube to provide an oil spray in the oil screen chamber. Here the incoming stream of air passes through the oil spray screen, mixes with the oil and then sweeps down through the screen [8 against the battle I 9 and the surfaces of the oil in the chamber 9. It then passes upwardly through the screen l2 and the filter material 13 and out through the discharge pipe 6 through the motor.

. It is thus cleansed of dust and dirt particles.

of details coming within the held of invention claimed maybe resorted to inactual practice if desired.

Having thus described the invention, what I claim as new and desire to secure by Letters Pat- .ent is:-

1. In an air cleansing device of the class described, a casing provided at its top with a cleansed air outlet and provided on one side with I an atmospheric air intake pipe. an oil screen chamber at the lower end of said pipe, an oil trough in said casing beneath said chamber, an oilelevating tubein said trough having its upper end extending into said chamber, and a heating pipe connected with said tube.

2. In an air cleansing device 01 the" class described, a casing provided at its top with a cleansed air outlet and provided on one side with 'an atmospheric air intake pipe, an oil screen receptacle being provided with an arcuate partition defining an oil trough and being further provided with an upstanding ported oil percolator tube, and a hot air heating pipe connected with said tube, said casing being provided with a partition disposed above said first named partition and defining an oil screen chambei-, said percolating tube having its discharge end extending into said chamber, an atmospheric air intake pipe on said casing discharging into said all screen chamber, and a cleansed air outlet connected with said casing.

4. Irra structure of the class described, an upright casing with an oil sump at the bottom and having a clean air outlet at the top, an atmospheric air inlet, and an oil screen chamber with which said inlet is connected together with motive gas operatedmeans in said casing for supplying oil spray to said oil screen chamber and 'means at the top'of said casing to filter out oil from the air and return it tosaid sump.

5. In an automotive appliance oi the class de-' scribed, comprising an upright casing with an oil sump'atthe bottom and having a cleaned air discharge at the'top, an atmospheric air intake, an internal oil screen chamber disposed intermediate the sump and air intake, an induction oil spray "tube extending into said chamber, and means atthe top or said casing to filter out oil from the airandreturnit tosaidsump.

6. In an air cleansing device oitheclass described, a casing provided with an .oil sump at the bottom and at its top with a cleansed air outlet and provided on one side with an atmospheric, air intake, an oil. screen chamber intermediate said intake and sump, an oil trough in said casing beneath said chamber, an-oilinduction tube insaid trough having its discharge end disposed to proiect an oil spray into said chamber, and oil filtering and collecting means in 'front of said air outlet and in free communication with said sump to return oil collected thereto. r

-7. In an air cleansing device of the class described, a casing providedv at its top with a cleansed air outlet and provided on one side with an atmospheric air intake Pipe. an-.oil screen chamber at the lower end oi-said pipe, an oil trough in said'caslng beneath said chamber,- an

induction oil elevating tube in said trough hav-- ing its upper end extending into said: chamber'and a motive gas pipe connected with said tube.

8. In an air cleansing device for internal oom-- bustion-engine's, a casing having an air-inlet and an outlet, a liquid sump in said casingbetween said inlet and said outlet, and a tubeior co'nnec casing below the level or said liquid and discharging exhaust gas from said engine into the liquid in said casing, the gas coming into direct contact with the liquid.

10. In an air cleansingdevice for-awe with an tion engine directly into said liquid causing said liquidt'obesprayedacrossaidairpathwithin said casing. Y
